I was playing the desktop version and decided to use Steam so I got achievements too.
I went to the folder in;
C:\Users\Steven\AppData\Local\Game Dev Tycoon\Local Storage
and moved the files to;
C:\Users\Steven\AppData\Local\Game Dev Tycoon - Steam\Local Storage
I then loaded Steam but it never recognised any. I then done the following;

But it didn’t work either. How can there REALLY not be a “load save game” option like every other game has had for over 20 years now?
